Can anyone suggest a good chain adjustment tool along with a cheap ish torque wrench for a V4 to buy online in the UK, I say cheap ish as ill only ever use it once or twice a yr and don't want to spend loads on one, also am I correct in thinking that the torque setting for the pinch bolts is 35nm
 
Any decent tool shop will have a d spanner selection,

I cant remember the size 75mm? but do quick measure and near enough is good enough for that job. You could used a drift of some sort, Ive used both with success.

Youll need 2 or three torque wrenches, but for the rear wheel nuts the best way Ive found it to mark it with paint and reset to the mark.
 
thanks paul for the reply, I was hoping for a recommendation on one to buy as I dont have anyway of measuring the size spanner I need and with all this lock down I cant visit a shop so intend to order on online and i want to get the right one along with a good torque wrench
 
If youre stuck use some kind of drift perhaps copper? Some use screwdrivers but thats a bit harsh on the ring. I just went and measured it- about 115 mm so a 4 1/2" hook spanner should do it.

Get the HDESA or equivalent hub tool from ebay or wherever. It’s flippin 30 bucks. It’s correct for the application. Please don’t use any kind of hammer an punch, that’s just not really a habit of improvisation you want to start adopting. Get the right tools for the job. Paul G not trying to debunk your methods but If you’re going to spend 30k on a bike and work on it yourself, it’s probably a good idea to do it correctly.
 
Although I agree with proper tools for the job, a hammer and punch if used correctly can adjust the chain with no damage to the bike or adjuster, just tap lightly.

I absolutely 100% recommend getting the tool as this is something you will do multiple times during bike ownership. However, if faced with not riding the bike, or the potential sprocket damage from riding with the chain too loose, adjust it with gentle taps of the ring with something like a plastic or wooden dowel and a hammer.

endodoc thanks for the reply, I am definitely not going to touch my bike until I get the right tools, can you point me in the right direction and could you provide a link to what you call a HDESA hub tool, ive tried google it but it doesn't provide any hub tools the OEM one as you state is expensive so I am happy to get one from ebay and the like I just need someone to suggest one and ill get it, I am probably over thinking this but I just want to get the right one first and not have the issue of sending stuff back etc and all the hassle that brings if I don't get the right one straightaway. while im asking questions am I right in saying that the pinch bolts torque setting is 35nm
 
yes That tool is what you need. As far as other “hub” tools are concerned, not sure what you are referencing. You need a tool to rotate the eccentric hub, a wrench to loosen (in a step wise fashion) the swingarm pinch bolts, and a torque wrench to tighten the pinch bolts. If you want to remove the wheels then of course you will need the socket to do so along with a torque wrench that will go to the appropriate spec. You will need additional tools if you want to physically remove the hub from the swingarm.
 
This tool works as well.


As for the torques I have seen 35nm referenced online. This is what the service manual states.

Im sure there was a service bulletin about the torque spec. I think it was changed to 20Nm. I would double check with your Ducati shop tho.
 
Chain tensioning is a critical, basic maintenance thing. I'm concerned if they can't get it right in the service manual and don't notify owners.

FYI, although 35Nm is referenced in videos I found online, the pictures I posted of the service manual state 25Nm. The way I worded it above was a bit misleading. I'd really like to know if there is updated info on the torque. My bike goes in next week for its first service. I will have to ask.

Always use the right tools agreed, however the aim is to get the job done without damage regardless of price. Unfortunately the first adjustment I did was replacing the original chain when I did the rear sprocket but the eccentric hub was locked solid from the factory could not get it to move with the spanner and it took a while with a heat gun and a bit of cautious tapping with a copper drift ground to the right shape to get it to move, zero damage to the ring, after that the hook spanner has been fine. Never been a big fan of these spanners, I've encountered problems in the past if you need to apply a lot of torque they can easily slip off, especially the thin pressed ones that are often sold for this job.
 
Thanks for all your help, ive gone ahead an ordered the one from Ebay so it will take a few days to get here, in the mean time if anyone can confirm the correct torque setting that would be good for us ALL.
